( Figs 79 , 129, 130 , 165 , 175 )

Platynoptera humeralis PIC, 1933: 17 .

Holotype ♂. Faro, Amazonas ( Brazil), Háhnel (MNHN) . CORPORAAL, 1950: 273.

Diagnosis: Within Platynoptera , only in specimens of this species is there a slight flavotestaceous streak that extends backwards from the humeral angle.

Description: Size: Length 10.0 mm; width 4.0 mm. Form: As in Fig. 165 . Color: Cranium mostly dark brown, vertex with small narrow flavotestaceous line; pronotum mostly black, upper sides and anterior margin flavotestaceous; elytral disc mostly black, with small narrow flavotestaceous streak at humeral angle. Head: Antennal capitulum very long ( Fig. 79 ), each capitular antennomere as long as combined length of scape, pedicel, and funicle; antennal carina very prominent; EW/FW 25/10. Thorax: Pronotal anterior margin not projected at middle, sides of disc slightly depressed; side margin of disc with shallow tubercle; PW/PL 60/65; elytra only slightly flared; disc without discal carinae; EL/EW 235/57. Abdomen: Male pygidium not incised at distal margin; aedeagus as in Figs. 129, 130.

Variation: Size: length 10.0-11.0 mm; width 4.0-4.5 mm. The dark macula on the pronotal disc may extend to the anterior margin of the pronotum. In a second specimen, the elytral disc shows a midelytral flavotestaceous fascia.

Natural history: A specimen was collected in February.
